CROSS-REFERENCE TO RELATED APPLICATION

This application claims the benefit of U.S. Provisional Patent Application Ser. No. 63/211,411, filed on Jun. 16, 2021, and incorporates the disclosure of the application in its entirety by reference.

BACKGROUND State of the Art

Various wheeled platforms, such as skateboards, are made of a platform or board and a variety of components, such as wheels and axles, which are connected to the board. The placement of the components, however, introduces instability by, for example, unequally distributing a rider's weight over the skateboard. Accordingly, the skateboard's riding capacity (i.e., the number of riders per skateboard) may be limited by an unequal distribution of each rider's weight over the skateboard. Furthermore, a second rider will invariably hold onto the rider in front for stability. Such an action can be dangerous since throwing the lead rider off balance will often result in a fall.

In a conventional skateboard, a first wheel assembly is attached to a front end of the board and a second wheel assembly is attached to a rear end of the board. The placement of one wheel assembly at one end and another wheel assembly at an opposite end, however, narrowly distributes each rider's weight over the skateboard, making the skateboard more prone to vibrations or wobbles, thereby limiting the skateboard's riding capacity to one.

Conventional methods for improving stability of a skateboard have not sufficiently addressed the need to provide a balance of nimbleness and stability while providing two riders with sufficient space to rest their feet on the skateboard.

Various representative implementations of the disclosed apparatus may be applied, for example, to any number of sporting environments, and the wheeled platform described is merely one exemplary application for the apparatus. Alternative embodiments may be applicable to non-sporting environments.

Referring to FIGS. 1-4 , an exemplary wheeled platform 100 may be used by a first rider 102 a and a second rider 102 b positioned in tandem with each other for propelling themselves across the ground or any other suitable surface by pushing the ground or surface with one foot (i.e., pushing foot) while balancing themselves on the wheeled platform 100 with another foot (i.e., non-pushing foot). According to various embodiments, the wheeled platform 100 may comprise a platform 105, a plurality of wheel assemblies 110, a first member 115 a for being grasped by the first rider 102 a, and a second member 115 b for being grasped by the second rider 102 b.

According to various embodiments, the platform 105 may comprise a top surface 106 and a bottom surface 107. The platform 105 may also comprise a first end 108 and a second end 109 opposite the first end 108. The first end 108 may be a rear end of the platform 105 and the second end 109 may be a front end of the platform 105, or vice versa. The platform 105 may be constructed from a variety of suitable wood materials or composite materials. For example, the wood materials may comprise birch, bamboo, maple, and the like. The composite materials may comprise aluminum, nylon, plexiglass, fiberglass, foam, and the like.

The platform 105 may comprise any suitable size or shape to provide sufficient space for the first rider 102 a and the second rider 102 b to rest their feet on the top surface 106 of the platform 105 so that the first rider 102 a and the second rider 102 b may ride in tandem with each other. As an example, the platform 105 may comprise a length of approximately 72 inches and a width of approximately 13 inches. In some embodiments, the platform 105 may be planar-shaped. In other embodiments, the platform 105 may be non-planar shaped with a raised rear end and/or front end.

In an exemplary embodiment, and referring now to FIGS. 2-3 , the plurality of wheel assemblies 110 may comprise a first wheel assembly 110 a, a second wheel assembly 110 b, and a third wheel assembly 110 c. The first wheel assembly 110 a may be coupled to the bottom surface 107 and positioned at the first end 108 of the platform 105. The second wheel assembly 110 b and the third wheel assembly 110 c may each be coupled to the bottom surface 107 and positioned at the second end 109 of the platform 105.

The first wheel assembly 110 a may comprise a first “truck” assembly 120 a, the second wheel assembly 110 b may comprise a second “truck” assembly 120 b, and the third wheel assembly 110 c may comprise a third “truck” assembly 120 c. The first “truck” assembly 120 a may comprise a first baseplate 121 a coupled to the bottom surface 107 of the platform 105, a first “hanger” (not shown) pivotally coupled to the first baseplate 121 a via a first kingpin 130 a and a first compressible bushing 135 a, a first axle 123 a, and a first pair of wheels 125 a connected to the ends of the first axle 123 a via a first pair of ball bearings (not shown). The second “truck” assembly 120 b may comprise a second baseplate 120 b coupled to the bottom surface 107 of the platform 105, a second “hanger” (not shown) pivotally coupled to the second baseplate 121 b via a second kingpin 130 b and a second compressible bushing 135 b, a second axle 123 b, and a second pair of wheels 125 b connected to the ends of the second axle 123 b via a second pair of ball bearings (not shown). Similarly, the third “truck” assembly 120 c may comprise a third baseplate 120 c coupled to the bottom surface 107 of the platform 105, a third “hanger” (not shown) pivotally coupled to the third baseplate 121 c via a third kingpin 130 c and a third compressible bushing 135 c, a third axle 123 c, and a third pair of wheels 125 c connected to the ends of the third axle 123 c via a third pair of ball bearings (not shown). Each baseplate 121 a, 121 b, and 121 c may be fixedly coupled to the bottom surface 107 of the platform 105 by any suitable mechanical connectors, such as rivets, screws, bolts, and the like.

In one embodiment, the second wheel assembly 110 b and the third wheel assembly 110 c may be coupled to the bottom surface 107 of the platform 105 in a front (or leading) position and a rear (or trailing) position, respectively, along a central longitudinal or lengthwise axis L of the platform 105. The first axle 123 a, second axle 123 b, and third axle 123 c may be substantially parallel to each other and perpendicular to the central longitudinal axis L of the platform 105 when the wheeled platform 100 is at rest.

The first member 115 a and the second member 115 b may be coupled to the top surface 106 of the platform 105 and extend vertically therefrom. The first member 115 a and the second member 115 b may be connected to the top surface 106 of the platform 105 via a first connecting member 140 a and a second connecting member 140 b, respectively. The first connecting member 140 a and the second connecting member 140 b may each comprise any suitable mechanical connector, such as a rivet, a screw, a bolt, and the like. The first member 115 a and the second member 115 b may be positioned along the central longitudinal axis L of the platform 105. The first member 115 a may be positioned proximate the first end 108 of the platform 105 and the second member 115 b may be positioned proximate the second end 109 of the platform 105. The first member 115 a and the second member 115 b may, however, be placed in any suitable position for being grasped by the first rider 102 a and the second rider 102 b, respectively.

The first member 115 a and the second member 115 b may allow the first rider 102 a and the second rider 102 b to lean to one side or the other to a significant degree without hindering the riders' ability to balance on the wheeled platform 100. As an example, when the first rider 102 a and the second rider 102 b want to turn or otherwise control the direction of the wheeled platform 100, the first rider 102 a and the second rider 102 b may grasp the first member 115 a and the second member 115 b, respectively, with one hand and/or both hands while leaning to one side or the other.

The first member 115 a and the second member 115 b may each comprise an adjustable height. The first member 115 a and the second member 115 b may each be twisted into a locked position by pressing the first member 115 a and the second member 115 b towards the platform 105 and turning the first member 115 a and the second member 115 b to lock into position. Similarly, the first member 115 a and the second member 115 b may be decoupled from the platform 105 by twisting the first member 115 a and the second member 115 b into the unlocked position by turning the first member 115 a and the second member 115 b to disengage. In some embodiments, a first handle (not shown) may be coupled to the first member 115 a and a second handle (not shown) may be coupled to the second member 115 b.

In operation, one or more riders, such as the first rider 102 a and the second rider 102 b, may be positioned in tandem with each other. Specifically, the first rider 102 a and the second rider 102 b may propel themselves across the ground or any other suitable surface by pushing the ground or surface with one foot (i.e., pushing foot) while balancing themselves on the wheeled platform 100. Each rider may balance themselves by resting their non-pushing foot on the top surface 106 of the platform 105. Once the wheeled platform 100 is in motion, the first rider 102 a and the second rider 102 b may rest both feet on the top surface 106 of the platform 105 and may turn, or otherwise control the direction of the wheeled platform 100, by shifting their weight from one side of the wheeled platform 100 to the other. When the first rider 102 a and the second rider 102 b lean to one side or the other by pushing or pulling the first member 115 a and the second member 115 b, respectively, the first axle 123 a, second axle 123 b, and third axle 123 c may rotate, in part, around an axis oriented perpendicular to the ground or other surface upon which the wheeled platform 100 is positioned. Accordingly, when the first rider 102 a and the second rider 102 b incline the platform 105 with respect to the plurality of wheels 110, the wheeled platform 100 may be steered in the direction of the lean. For example, both the first rider 102 a and the second rider 102 b may steer the wheeled platform 100 in a rightward direction by holding onto the first member 115 a and the second member 115 b and leaning in the rightward direction. Similarly, the first rider 102 a and the second rider 102 b may steer the wheeled platform 100 in a leftward direction by holding onto the first member 115 a and the second member 115 b and leaning in the leftward direction.
